Spoiler
If you look at the opening, where it shows the title it has a count up.
01 is in black, 02 in yellow, 03 in blue, 04 in pink, 05 in green 06 in a brownish color, probably bronze, and 07 in a grey, which then glows white before turning into the 7 in the title.
With Phone Braver 01 being black, phone braver 03 being Blue, and 07 being Silver, it's seems likely that the other 4 phone bravers are the same colors as the colors shown in the opening count up.

Anyways, over all great episode, and who can't help but watch the phone fight a few extra times.
